1 The transporting of vast quantities of sand causes strong sandstorms, which limit visibility and cause injuries to man and agriculture. At times the storm is so vast that it manages to encompass a broad geographical area (...)

2 The strong transporting of hot air causes a temporary but considerable rise in temperature, of at least 5-6° above average - and at times even 25-30° above the average - in the affected areas.
